Windows 10: Unable to Update to Windows 11

I am trying to update my Windows 11 software to the current version. And I am getting error messages that I am unable to. I am getting an Install Error Code 0xc1900201, so I don't have enough space. Here is what I have on my computer now. I am stuck right now with what I need to do.

Unable to upgrade Windows 11 Home to 11 Pro

Thanks much, Dave, indeed it was a big job.

Clean install of Windows 11 from a bootable USB helped to Activate the Pro.

Just to summarize what was done:

1. Took backup of the drives and save some on cloud.
   
2. Installed the Media creation tool app as you suggested (Download Windows 11)
   
3. Connected the USB and ran the application and downloaded the Windows 11.
   
   1. additional thing which I had to do is to install WLAN driver to the USB in advance, to have the WIFI option available as it was required to connect to a network to download the latest windows features while reinstalling the Windows, and Wi-Fi option was not available.
      
4. Turned off the 'Secure boot' from the BIOS menu.
   
5. Changed the 'Boot Order' in the BIOS menu to first use the USB Boot.
   
6. Saved and Exit, which triggered Restart and Windows installation.
   
7. During the network connecting stage to install the latest updates and features - 'Let's Connect you to a network', I opened the CMD (Shift + F10) and ran than WLAN driver exe to install it and then I was able to connect to my WIFI network.
   
   1. Optional to this step is to BYPASS the network connection stage by following this - bypass "lets connect you to a network" - Microsoft Community
      
   2. Then, doing that manually once Windows has been installed.
      
8. Once everything is set-up, I followed the suggestion from this again, and it worked - Unable to upgrade Windows 11 Home to 11 Pro - Microsoft Community
   

 

Windows Updated(16299.309).KB4088776 Restart is required to complete.

Hi dalchina. Good news, I followed your suggestion and reinstalled the update and now it appears as "installed correctly" *Biggrin Maybe it was not necessary to run the Windows Update Troubleshooter or maybe if necessary. But using it I do not think it could have worsened something. The installation was very fast, unlike the first time it showed step 1 and step 2 completed.

Thanks for the suggestions and for the time to respond Best regards.


And thanks for the tip of that program, I'll have it on my list.

 

Windows Updates failed to instal

I'm not sure how differant XP media center Edition is but you could clear the history \ cache if these folders are there.

Step 1 Register DLL files.

=================

By trying this step, we can check if the update engines are working properly.



1. Close all instances of Internet Explorer.

2. Click Start and Run, type "Regsvr32 atl.dll" (without quotes) in the Open box and click OK.



Note: There is a space between regsvr32 and atl.dll



3. Similarly, one by one, register the files listed below:



Regsvr32 msxml3.dll

Regsvr32 wuapi.dll

Regsvr32 wuaueng.dll

Regsvr32 wuaueng1.dll

Regsvr32 wups2.dll

Regsvr32 wucltui.dll

Regsvr32 wups.dll

Regsvr32 wuweb.dll

Regsvr32 qmgr.dll

Regsvr32 qmgrprxy.dll

Regsvr32 jscript.dll



Note: If you encounter errors while registering any of these files then skip that file and continue with the next one.



If the issue persists, let's move on to the steps below to verify Windows Update services and temporary folders.



Step 2 Verify the relevant Windows Update services.

=========================================

1. Click Start->Run, type "services.msc" (without quotation marks) in the open box and click OK.

2. Double click the service "Automatic Updates".

3. Click on the Log On tab, please ensure the option "Local System account" is selected and the option "Allow service to interact with desktop" is unchecked.

4. Check if this service has been enabled on the listed Hardware Profile. If not, please click the Enable button to enable it.

5. Click on the tab "General "; make sure the "Startup Type" is "Automatic" or "Manual". Then please click the button "Stop" under "Service Status" to stop the service.

6. Then please click the button "Start" under "Service Status" to start the service.

7. Please repeat the above steps with the other services:



Background Intelligent Transfer Service

Event Log

Remote Procedure Call (RPC)



Note: Event log service is enabled on all of the hardware profiles; this service does not have an option to enable or disable on certain hardware profile.



If it still does not help, let's proceed to step 3.



Step 3 Reload the Update temporary folders.

===================================

One possible cause is that the temporary folder for Windows Update is containing corrupted files. Let's erase all the files there to get the system clean.



1. Click Start, Run, type: cmd and press Enter. Please run the following command in the opened window.



Net stop WuAuServ



2. Click Start, Run, type: %windir% and press Enter.

3. In the opened folder, rename the folder SoftwareDistribution to Sdold.

4. Click Start, Run, type: cmd and press Enter. Please run the following command in the opened window.



Net start WuAuServ



Please test the Windows Update website and let me know the result. If the issue persists, to clarify the issue and provide more accurate troubleshooting steps, please assist me in collecting the following information.
